Abstract:

Semiconductors are widely detected in the natural environment, and microbes are one of the most abundant living organisms on the earth. Semiconductor-microbe hybrid system plays a key role in many fields, such as deeply degradation and mineralization of refractory pollutants, synthesis of value-added chemicals, and bio- geochemical cycles of elements. The key factor between semiconductors and microorganism centers on the electron transfer mechanism and pathway on the abiotic/biotic interface. Therefore, this review focused on the electron transfer on semiconductor-microbe interface, and summed up the functional types of microorganisms, types of semiconductors and photocatalytic mechanism on the biotic/abiotic hybrid system. Direct and indirect electron transfer pathway on the semiconductor-microbe interface were summarized. Methods of enhancing electron transfer methods were also introduced, including direct electron transfer enhanced by semiconductor modification, reducing photo-electrons and holes recombination, and indirect electron transfer enhanced by electron shuttles and carriers. At last, this paper introduces the application of the semiconductor-microbe hybrid system in the environmental field over recent years, including refractory pollutants synergistic degradation, value-added chemical synthesis, and elemental bio-geochemical cycling on the earth. We hope this review will help researchers to strengthen the understanding of the semiconductor-microbe interface, and propose solutions for the design and applications of the hybrid semiconductor-microbe system in the environmental field.
